Wallbox Pulsar Plus 40A NACS Review

A factory Tesla-style plug on the smallest charger we track, in the one configuration that goes on a NEMA 14-50 outlet instead of into your panel. Forty amps is the ceiling and there is no 48-amp version you can unplug - from Wallbox or from anyone.

By Stephen V.Last updated How we pick

Almost every native-NACS home charger is a hardwired fixture. That makes sense — NACS buyers tend to be Tesla households installing a permanent charger — but it leaves out everyone who rents, everyone whose panel is full, and everyone who already has a NEMA 14-50 outlet on the garage wall and no desire to pay an electrician to remove it. This is the one that plugs in: a factory NACS cable on a 14-50 plug, no adapter and no electrician.

It is also, by a wide margin, the smallest charger on this site. Wallbox’s own datasheet gives 7.8″ × 7.9″ × 3.9″ and 4.4 lbswithout the cable — against 24.25 lbs of cast aluminum for a Grizzl-E Ultimate. On a tight garage wall, beside a door, or in a condo parking stall, that is not a specification, it is the reason you can install it at all.

The catch is the amperage, and it is a real one: 40 amps / 9.6 kW is the ceiling, with no 48-amp option in this configuration. Below is every figure Wallbox publishes, the arithmetic on what those eight missing amps actually cost you, the three features footnoted as needing a separate accessory, and an honest read on who should buy a different charger.

#1Best NACS you can unplug

Wallbox Pulsar Plus 40A NACS

The only NACS charger here you can unplug and take with you — and the smallest by a wide margin, at 4.4 lb and under eight inches square without the cable. It is also the only one that publishes both OCPP and dynamic load management, so it is the NACS pick for a tight garage, a rented wall or a panel with nothing spare. The catch is the amps: Wallbox's plug-in model is 40A, full stop.

Strengths

  • Plugs into a NEMA 14-50 outlet with a factory NACS cable — no adapter, no electrician
  • Genuinely tiny: 7.8 x 7.9 x 3.9 in and 4.4 lb without the cable
  • OCPP 1.6j plus static and dynamic load management, and ENERGY STAR certified

Trade-offs

  • 40A / 9.6 kW is the ceiling — Wallbox's 48A model is hardwired only, in NACS as in J1772
  • The priciest way to get 40 amps in this registry
  • Load management and solar charging are both footnoted 'may require power meter accessory'

Our charging-speed math. At 40A (9.6 kW) and ~3.5 miles per kWh, about 34 miles of range per hour. The hardware current selector starts at 16A and the app will take it down to 6A, so it can be fitted to whatever circuit the panel can spare.

Build note. Model PUP2 in Wallbox's own numbering: 25 ft cable, 7.8 x 7.9 x 3.9 in and 4.4 lb without the cable, indoor and outdoor NEMA Type 4 per UL 50E, operating -22F to 104F and storage -40F to 158F, 208/240 V. Current is set by a hardware selector from 16A to the rated current and in software from 6A, with optional dynamic adjustment by an energy-management system. Wi-Fi and Bluetooth through the Wallbox app and portal, OCPP 1.6j, static and dynamic load management, solar charging and schedule planning — the last three each footnoted 'May require power meter accessory'. UL certification (NRTL) to UL 2594 and UL 2231 with an integrated CCID20 and 20 mA ground monitoring, FCC Part 15 Class B, and ENERGY STAR certification: Yes.

Specs read from the manufacturer spec sheet, on October 24, 2026. “Not published” means the brand does not state that figure.

The plug is the whole argument

There are good native-NACS chargers. Nearly all of them are bolted to the wall and wired into the panel, which makes them a decision you cannot reverse and a thing you cannot take with you. This one goes on a NEMA 14-50 plug with a factory NACS cable on the other end, and that combination is genuinely rare: of the chargers we track, it is the onlynative-NACS wall unit that plugs in rather than being hardwired — the one other NACS charger with a plug on it is a portable, not something you mount.

That matters in three situations, and only three. You rent. A hardwired charger is close to a fixture and stays with the building; this one comes off the wall in a minute and goes in the car. Your panel is full.A plug-in install uses a circuit that already exists instead of adding a 60-amp one you may not have room for — see our small-panel picks for how often this is the binding constraint. The outlet is already there. If a 14-50 is on the wall from a previous owner, an RV, a welder or a dryer, you can be charging today for the cost of the charger and nothing else.

If none of those three describes you, be honest with yourself about this purchase: you are paying a premium for a plug you will never unplug, and a hardwired 48-amp charger is the better buy. Our portable versus wall-mounted comparison works through that trade properly.

Why 40 amps, and what the eight amps cost

This is the number people get wrong about this charger, so it is worth being exact. Wallbox’s datasheet lists two electrical modelsin one body: a 40A model at 9.6 kW whose connection type is “NEMA 14-50 or hardwired”, and a 48A model at 11.5 kW whose connection type is “Hardwired”. Read against the part-number structure — which codes the connector, the power and the version independently — the published combinations mean there is no 48-amp Pulsar Plus you can unplug, in J1772 or in NACS.

It is not a derating of the bigger unit. It is a different electrical model, and the reason is code rather than marketing: the NEC treats EV charging as a continuous load, so the circuit must be rated at 125% of the charger’s output. Forty amps × 1.25 = 50, which is exactly what a 14-50 outlet is fed by. Forty-eight amps would need 60, and no residential plug is rated for that. This is why every plug-in charger sold in North America caps at 40 amps, from every brand.

So what do the eight amps cost? At 240 volts, 40 amps is 9.6 kW and 48 amps is 11.52 kW. At our reference of about 3.5 miles of range per kWh, that is roughly 34 miles of range per houragainst about 40 — a difference of six. Over a ten-hour overnight charge, sixty miles. Put the other way: if you drive less than about 300 miles a day, both chargers finish the job before you wake up, and the difference is invisible. Our charging-time guide runs the same math for specific battery sizes.

And the usual caveat applies with more force than normal here, because many NACS-port cars are Teslas: the car’s onboard charger sets the real ceiling. If your vehicle accepts 32 or 40 amps on AC, this charger is already at the limit and the 48-amp units would deliver nothing extra. The onboard-charger guide explains why the box on the wall is not really the charger at all.

Four and a half pounds

The spec that does not read as important and repeatedly turns out to be: 7.8″ × 7.9″ × 3.9″ and 4.4 lbs without the cable, published by Wallbox.

For comparison, inside our own registry: the Grizzl-E Ultimate is 24.25 lbs of cast aluminum in an enclosure of 10.25″ × 6.25″ × 3.75″, and the Autel AC Elite Home 50A is 13.2″ × 7.4″ and about 15 lbs. The Pulsar Plus is under eight inches square and weighs about what a laptop does.

Three practical consequences. It mounts on substrates that will not take twenty-four pounds — the backplate is included, and a renter’s wall or a plasterboard garage is a different proposition at 4.4 lbs. It fits where a bigger unit does not: beside a door that has to swing, in a narrow condo stall, between a window and a service panel. And it is genuinely portable — not a trunk unit like a true portable charger, because it still needs mounting to use properly, but light enough that taking it when you move is a decision rather than a project.

What it does out of the box, and what needs an accessory

Wallbox publishes more software capability than most of this category, and it also footnotes some of it — which we would rather print than paraphrase.

Included: WiFi and Bluetooth through the Wallbox app and portal, user identification and permission management with User / Admin / Super Admin roles, play / pause / lock, schedule planning, an RGB LED halo for status, and OCPP 1.6j. Current is set two ways — a hardware selector from 16 A up to the rated current, and softwarefrom 6 A up — so the unit can be fitted to a circuit smaller than 50 amps if that is what the panel can spare.

Footnoted:“Static Load Management, Dynamic Load Management” and “Solar Charging supported” both carry the note “May require power meter accessory”, as does the energy-management side of current adjustment. Wallbox’s own US page listed that accessory at $299.00 when we last read it. If load managementis the reason you are considering this charger — sharing a circuit rather than upgrading a panel — that accessory is part of the price, and it should be in the comparison from the start.

One documented incompatibility, also from Wallbox’s own page: solar charging “is not compatible with multiple-charger installations and OCPP”. So the open protocol and the solar feature are mutually exclusive, which is an unusually specific thing for a maker to publish and exactly the kind of detail that decides a solar install.

Build, listings and the temperature ceiling

The safety paperwork is thorough: UL Certification (NRTL) to UL 2594 and UL 2231, an integrated CCID20 with 20 mA ground monitoring per UL 2231, FCC Part 15 Class B, and ENERGY STAR certification— the last of which is the most common eligibility filter in utility rebate programs and is certified per model rather than per connector, so the NACS SKU and its J1772 twin stand together on eligibility.

The enclosure is “Indoor & Outdoor: NEMA Type 4 per UL 50E” — which by NEMA’s own definitions means windblown dust, splashing and hose-directed water, a genuine outdoor rating though not the corrosion-resistant 4X.

And then the one figure we would flag hardest, because it is the lowest in our registry: the operating range is -22°F to 104°F, with storage from -40°F to 158°F. The cold end is competitive — the same -22°F that Grizzl-E, Emporia and EVIQO publish. The hotend is not. Autel publishes 131°F for its unit and Grizzl-E, Emporia and EVIQO all publish 122°F; Wallbox publishes 104. A closed garage in Phoenix, a west-facing wall in Texas in August, or a carport in direct afternoon sun can all exceed 104°F, and this is the one charger we track where that is worth checking rather than assuming. Storage to 158°F tells you the unit survives the heat; the operating figure tells you where Wallbox stops guaranteeing it charges.

Who should buy it — and who should skip it

Buy itif you drive a Tesla or another NACS-port car and you need a charger that plugs in: because you rent, because the panel is full, because the 14-50 is already on the wall, or because the wall itself cannot take twenty-four pounds. In that situation it is close to unique — a factory NACS cable with no adapter in the chain, on the smallest body in the category, with ENERGY STAR for the rebate form, OCPP for the long term, and real UL listings behind it.

Skip it if you are hardwiring anyway. If an electrician is coming regardless, the same money buys 48 amps and a permanent install. The Lectron Nexus NACS is the hardwired native-NACS unit we rank first, and our NACS roundup covers the field.

Skip it if your household has a J1772 car, or might. You would be buying a connector problem rather than solving one: the NACS-to-J1772 adapter direction is the one two automakers have published cautions about, as our cable guide documents. The J1772 Pulsar Plus is the same hardware and charges a Tesla through the adapter the car came with.

Skip it if 40 amps is all you need and price is the priority. This is the most expensive way to get 40 amps in our registry by a clear margin. If the plug and the small body are not specifically what you are paying for, the 40-amp fieldhas units at a fraction of the price delivering identical charging — and if it is specifically a NACS plug on a budget, the Lectron portable Tesla charger is 40 amps with a native NACS plug in something you can keep in the trunk.

Skip it if the charger is going somewhere genuinely hot.The 104°F operating ceiling is the lowest we track, and in the Southwest that is a real constraint rather than a technicality.

Frequently asked questions

Can I get the Pulsar Plus NACS at 48 amps?

Not on a plug, and the reason is in Wallbox's own datasheet rather than in a marketing decision. The electrical table lists two models: the 40A model's connection type is 'NEMA 14-50 or hardwired', and the 48A model's is 'Hardwired'. The part-number structure codes the connector independently of the power and the version — '1' for Type 1, 'T' for NACS, '5' for 9.6 kW, '6' for 11.5 kW, 'C' for hardwired, 'N' for NEMA 14-50P — and reading those two tables together, there is no published combination of 48 amps and a plug in either connector. This is not Wallbox being awkward: code caps a plug-in charger at 40 amps on a 50-amp circuit, so no brand sells a 48-amp charger you can unplug.

How fast does the Pulsar Plus 40A NACS charge?

Forty amps at 240 volts is 9.6 kW. At our standard reference of about 3.5 miles of range per kWh, that is roughly 34 miles of range per hour — so a 40-mile commute is back in a little over an hour, and an almost-empty 75 kWh battery takes most of a night. The 48-amp hardwired units deliver about 40 miles per hour, which is six more. Over a ten-hour overnight charge the gap is about sixty miles, which is more than most people drive in a day and less than most people imagine when they are choosing between the two.

Do I need an electrician to install it?

Not if you already have a NEMA 14-50 outlet where you park, which is the whole argument for this configuration. You mount the backplate Wallbox includes, hang the unit and plug it in. If you do not have the outlet, you are hiring an electrician either way — and at that point the honest advice is to have them hardwire a 48-amp unit instead, because you are paying for the visit regardless and hardwiring is the cheaper, cleaner end of the job. One caveat worth raising with whoever does the work: a plug-in install outdoors generally wants an outdoor-rated GFCI breaker upstream, and local code is the authority on that.

Will it charge a non-Tesla EV?

Only with a NACS-to-J1772 adapter, and that adapter direction is the one automakers have published cautions about — so think carefully before buying this for a mixed-connector household. Volkswagen states in writing not to use its NACS adapter with any Level 2 AC charger, and Kia lists no J1772-to-NACS AC adapter at all while naming a J1772 charger on its own EV6 pages. If your household has, or might have, a non-NACS car, buy the J1772 Pulsar Plus — it is the same hardware with a different cable — and let the Tesla use the adapter it came with, which is the direction that works reliably.

What does the power meter accessory do, and do I need it?

It is the honest footnote on this charger's feature list. Wallbox's datasheet marks three features — 'Dynamic Load Management', 'Solar Charging supported' and the energy-management side of current adjustment — with the note 'May require power meter accessory'. So the charger schedules, locks, reports status and sets its own current out of the box, but the two headline features people buy Wallbox for are a second purchase. Wallbox's own US page listed that accessory at $299.00 when we last read it. If load balancing is why you are here, price the accessory into the comparison before you decide.

Is it rated for an outdoor wall?

Yes, with one published limit worth knowing if you live somewhere hot. The datasheet gives 'Indoor & Outdoor: NEMA Type 4 per UL 50E' — windblown dust, splashing and hose-directed water — with storage from -40°F to 158°F. But the operating range is -22°F to 104°F, and that 104°F upper bound is the lowest ceiling of any charger we track: the Autel publishes 131°F and Grizzl-E, Emporia and EVIQO all publish 122°F. In a Phoenix or Las Vegas garage in July, or on a wall in direct afternoon sun, that is a figure to take seriously rather than a rounding difference.

Does it support OCPP?

Yes — OCPP 1.6j, published in the datasheet, and Wallbox is one of only two brands in our registry that publishes an open protocol at all (Grizzl-E is the other). That matters for a reason most product pages never explain: OCPP means the charger can in principle be managed by software that is not the manufacturer's, which is the insurance policy against a brand discontinuing its app. One documented conflict to know about, from Wallbox's own US page: solar charging 'is not compatible with multiple-charger installations and OCPP', so you cannot have both of those features at once.

What does Wallbox's warranty cover?

Wallbox publishes a three-year warranty for the Pulsar Plus line, and we carry that figure for this unit. Worth being precise about where it comes from, though: the NACS datasheet itself has no warranty row at all, so the three years is the line-level term from Wallbox's product pages rather than a SKU-specific published figure for the NACS plug-in version. Three years is the standard term across most of this category — our longest-warranty roundup has every published term in one table, including the units that publish none.

The part-number structure confirms both a Type 1 and a NACS EVC code and both a hardwired and a NEMA 14-50P version code. RE-READ October 24, 2026 for the NACS roundup and the Grizzl-E head-to-head: the document is byte-for-byte the same version (…_NACS_EN_b, 10/25) and every figure above verified again. Two details worth pulling out of the part-number table explicitly, because they decide what can be bought: the EVC position codes '1' for Type 1 and 'T' for NACS, and the version position codes 'C' for hardwired and 'N' for NEMA 14-50P, with the power position offering '5' for 9.6 kW and '6' for 11.5 kW. Read against the electrical table - where the 40A model's connection type is 'NEMA 14-50 or hardwired' and the 48A model's is 'Hardwired' - the published combinations mean there is NO 48-amp Pulsar Plus on a plug in either connector, so 40A / 9.6 kW is the ceiling for any Pulsar Plus you can unplug. RE-READ October 31, 2026 for the Pulsar Plus NACS review, and the document is again the identical version (…_NACS_EN_b, 10/25) with every figure verified a third time. Three absences worth recording as findings rather than gaps, because a review has to say what is NOT on the sheet: there is NO warranty row anywhere in the datasheet (the 3-year term this site carries for the unit is Wallbox's published line warranty, not a figure from this document), there is NO amperage-step list of the kind Autel and ChargePoint publish (Wallbox gives a continuous hardware range of '16A to rated current' and a software range of '6A to rated current' instead), and there is NO stated circuit or breaker requirement for either model. The full part-number decode, verbatim: A Model 'PUP1 / PUP2 Pulsar Plus North America'; B Output 'U 25ft'; C EVC '1 Type 1' and 'T NACS'; D Power '5 9.6 kW' and '6 11.5 kW'; E Version 'C Hardwired'; F Custom 'N NEMA 14-50P'; G Color 'XX Custom' and '2 Black' — which makes the plug-in NACS SKU this review covers Wallbox's own PUP2-U-T-5-N-2 (accessed October 31, 2026)
